Absolutely. The main game isn't especially difficult and the only need for minmaxing really comes in when you're looking at the harder DLCs. I never finished grinding for Apotheosis but I had something like 17 stat capped units (sans str/mag on units that didn't need those) most of which having ideal skill sets and whatnot (never forget grinding out 20 different limit breaker scrolls). But for the main game none of that is required whatsoever.
I've played FE7 to 14, excluding 12 (and I do have the patch for that (and for 6)), and so far I have varying forms of appreciation for most of them except maaaaaaaybe Shadow Dragon. Not to say I didn't like it, but, as mentioned, the characters did feel pretty flat (especially when I'd already played Awakening with its focus on supports by then) and that's one of the things I look for most. I'm a lot more likely to have fun when I've got a bunch of favorite characters (looking at you, Lute and Marisa) and the only one I remember liking very well in Shadow Dragon was Catria. ... maybe Tiki. Nagi was pretty but.... she didn't matter at all?? idk.
I almost played FE4 for reasons thanks to Scarlet, but, I feel like the chapter lengths would kill me, and I can't imagine playing such an older game after everything else. It's the reason I haven't played through pokemon white 2 yet, even though I have a physical copy right here.
That said, I really like the new games for a number of reasons but interestingly enough, the game that snuck up on me and surprised me was Radiant Dawn. Obviously I needed to emulate it and my computer isn't the best, and I stopped playing at Part 4 Chapter 2 a million years ago and wasn't especially invested in it at the time. I picked it back up at that spot recently for reasons and I actually regret not having finished it at the time. This endgame is hype, and I'm still only on 4-E-4. It kind of sucks that I didn't really know how it worked and I didn't take everything from all the units I wasn't taking with me, but so far I've been making it work anyway. People complain about the support conversations in this game (or lack thereof) and they're totally justified, but in the parts I'd not finished I realised that some bosses have conversations with a surprising number of the player's units before fighting. I think Numida had a conversation with everyone I tried to attack him with, and Edward even had something to say when he tried to snipe him with his Purge tome. And [REDACTED] in 4-E-3 has conversations with units not even remotely relevant to him as far as I know (i.e. Sothe). I thought that was neat.
Of the GBA games, all two of them that I played, I definitely prefer Sacred Stones over Blazing Sword although I did like the length of Blazing Sword more than Sacred Stones' route split. I played 8 -> 7 and then started to play 6 but decided I wasn't going to play another 2D FE and jumped to Path of Radiance instead. One day I'll get back to 6.
Currently I've played through Awakening the most but I don't really think I can pick any one favorite. If I actually owned Radiant Dawn and could play it at full speed that might be different. It's probably between Awakening and Fates because I'm anime trash and like being able to associate with cute girls, sue me they're newer and are both visually and uh, the audio equivalent of "visually" - i can't think of the word right now - pleasing. People have their opinions which is fine but I feel like they've been improving in all the areas I really care about.
